Mesh Roads have no collisions in World Editor 2

When creating Mesh Roads in the old World Editor, they had built-in collisions. But in the new World Editor, they have no collisions and I can't find a way to add this.
I have looked through the forums and on the new documentation but cannot see any reference to this issue (so it might be me)
Does anyone know how I can enable/fix this?

 

Haven't messed with WE 2 but sometimes a game restart is needed?

 

Yes, that worked. I feel a bit silly now. Because of the behaviour in the old World Editor, I was expecting a new setting for the new World Editor. It seems a bit of a backward step though. Thank you.

 

Saving and reloading the map is enough, but it's clearly a bug that needs to be fixed.
